FIELD OF THE INVENTION

This invention relates to a media storage disc repairing apparatus, and more particularly is to an improved repairing apparatus with an abrasive pad system to clean the surface of a damaged or dirty disc.

DISCUSSION OF RELATED ART

Media storage discs such as compact discs (CD), digital video discs (DVD) or video compact discs (VCD) have rapidly gained popularity with consumers. Compact discs (CDs) have been the preferred media format for storing and retrieving infrequently accessed digital information. While the compact discs are a very effective, durable and economical means of storing and transporting digital data and information, it is also a fact that they get tampered and damaged very easily. The most common form of damage is the scratch on the read-side of the disc. In addition, even with proper care and handling, they can easily get scuffs. Grease, dust, exposure to excess heat, and rough handling can result in damage and may affect the quality of the stored data.

There are various known processes to repair scratched discs for temporarily or permanently. U.S. Pat. No. 5,102,099 issued to Brown on Apr. 7, 1992 discloses a disc polisher apparatus having rotating polishing pads which in association with an abrasive compound repair the damaging scratches. The disc rests upon a disc platform having a biased shaft, and is positioned slightly above the polishing pads. The polishing pads do not allow an even amount of pressure to be applied to the surface of the disc. The uneven pressure distribution on the disc may lead to more destruction of the scratched disc.

Use of centrifugal force for dispensing cleaning solution across the face of a disc is disclosed by U.S. Pat. No. 5,126,992 issued to Lavinsky on Jun. 30, 1992. Such a disc cleaner incorporates brushes or abrasive pads which mechanically rub the surface of the disc to remove particulate matter on the surface of the disc. Further, dried liquids, fingerprints and other contaminants can not be sufficiently removed.

U.S. Pat. No. 4,654,917 issued to Yeung on Apr. 7, 1987 explains an apparatus that includes a cleaning pad fastened to a rotatable carrier disposed in a housing carrier. The carrier and its cleaning pad exhibit planetary motion such that the cleaning pad concurrently rotates and revolves. While the apparatus is satisfactory for removing contaminants from the surface of the disc, such apparatus is inadequate for applying the forces necessary for buffing the surface of the disc to remove scratches or marks from the entire surface of the disc.

U.S. Pat. No. 4,825,497 issued to Nagao on May 2, 1989 provides a disc cleaner comprising a main casing, and a mounting structure located in the main casing to receive a disc to be cleaned. A lid operatively engaged with the main casing covering an upper surface of the main casing. A cleaner is mounted on an inner surface of the lid. A driving mechanism is operated when the lid is positioned in a closed condition relative to the main casing. Such an arrangement does not maintain a parallel or substantially parallel position of the disc against an abrasive surface while the cleaning operation.

Therefore, there is a need for an apparatus that allows uniform distribution of pressure on the surface of the disc. Further, such a disc cleaner would incorporate brushes or abrasive pads to rub the surface of the disc mechanically and would adequately apply the forces necessary for buffing the surface of the disc. Moreover, such an apparatus would maintain the parallel or substantially parallel position of the media storage disc against the abrasive surface while cleaning The present invention accomplishes these objectives.

The housing includes a visible compartment at a top portion thereof to accommodate the platform. The media storage disc is secured to the platform by at least one locking mechanism. The media storage disc is placed on the platform with the bottom surface facing upwards. The locking mechanism may be utilized to interlock a top of a top portion of the shaft to securely fasten and stabilize the media storage disc.

The apparatus further includes an abrasive pad system attached to a bottom side of the upper lid. The abrasive pad system includes an abrasive pad holder attached to the upper lid by way of a ball bearing. The bottom side of the abrasive pad holder includes a male connecting part thereof. A female connecting part of a plurality of abrasive pads is connected to the male connecting part of the abrasive pad holder. At least three springs are evenly arranged between a top side of the abrasive pad holder and a bottom side of the abrasive pad holder. The springs distribute an even amount of pressure to the bottom surface of the media storage disc. The plurality of abrasive pads is fixed to the bottom side of the abrasive pad holder.

An elongated rotatable shaft, is further included that is fixed to a center of the platform coupled to a motor encased in the housing. The upper lid of the housing is closed and the media storage disc is sanded by means of an abrasive sand paper with an adhesive that may be attached to one of the abrasive pads. Then the media storage disc is buffed by a new abrasive pad and the polishing compound is applied. The media storage disc is waxed with another abrasive pad along with the waxing compound placed thereon. The sanding, buffing, and waxing can be initiated by powering “on” the motor encased within the housing by a plurality of buttons.

The present apparatus facilitates uniform distribution of pressure on the surface of the media storage disc. Further, such a media storage disc cleaner incorporates brushes or abrasive pads to rub mechanically the surface of the media storage disc and adequately applies the forces necessary for buffing the surface of the media storage disc. Moreover, such an apparatus maintains the parallel or substantially parallel position of the media storage disc against the abrasive surface while cleaning Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.
